CGP52411 (DAPH) is a high selective, potent, orally active and ATP-competitive EGFR inhibitor with an IC50 of 0.3 μM. CGP52411 blocks the toxic influx of Ca2+ ions into neuronal cells, and dramatic inhibits and reverses the formation of β-amyloid (Aβ42) fibril aggregates associated with Alzheimer's disease.

How to use

In Vitro:

CGP52411 (DAPH; 0-100 μM; 90 minutes; A431 cells) treatment inhibits autophosphorylation and c-src autophosphorylation in vitro in a dose-dependent manner with IC50s of 1 μM and 16 μM, respectively. CGP52411 treatment also shows a concentration-dependent reduction in tyrosine phosphorylation of p185c-erbB2 with an IC50 value of 10 μM. CGP52411 (DAPH) inhibits c-src kinase with an IC50 value of 16 μM. CGP52411 inhibits PKC isozymes isolated from porcine brain with an IC50 of 80 μM. CGP52411 inhibits conventional PKC isozymes (cPKCs α, β-1, β-2, and γ) but not nonconventional PKC isozymes (nPKCs δ, ε, and ζ) or atypical PKC isozymes (aPKC η).

In Vivo:

CGP52411 (3.2 mg/kg, 6.3 mg/kg, 12.5 mg/kg, 25 mg/kg, and 50 mg/kg; oral administration; daily; for 15 days; female BALB/c nude mice) treatment in vivo against xenografts of the A431 and SK-OV-3 tumors, and has antitumor activity.
